The Serpent Project 4X PRO is a logical evolution over the 4X EVO. it shares all features of the 4x evo including the same easy to build and setup shock system and fixed-length pullrods, while the vertical topdeck is replaced by a horizontal topdeck for more aggressive steering on high grip surfaces and the rear suspension is heavily modified with much longer arms and a different geometry to create more steering and widen the setup window on medium to high grip asphalt. For maximum rear stability and steering precision which is needed in stock classes, there is a fixed-toe rear wheelcarrier included in the kit.
